Yeh probably right about the cold start. I think of it this way. Imagine what other cars the owner must be having not to drive the Z! If you go through that thread u will see that there is a forum member with a Z tune with almost the same milleage!

Came across this today! Car has only 39km and never driven since delivery. http://www.gtr.co.uk/forum/upload/94523-nismo-z-tune.html Isn't 2300rpm is bit too much for idle? but who cares...

2008 Freelander

Correct:) Its the convertible. I thought its gonna be bit harder to guess because of the color!!

Ela!! Not too soon bro. Guess this if u can.

Merc CLK GTR

LOL Ok my last try. Is it a Ferrari F40?

Does it have 3 round lights each end or just two?

Mclaren F1 Road Car or Saleen S7?

Brief minute contacts are oil films on the liners which does not have direct contact with the oil in the sump. These oil get burned in the chamber and goes out with the exhaust gas. Compression gets less when piston rings are worn, oil gets into the chamber when oil rings are worn. And about "Tolerence get wider". Thats why u have rings which are spring loaded. never heard of new cars needing regular topping up. Give some examples please.

Where did I mention about me buying new cars every 100,000kms? I think u r not only competent enough about engines but also understanding simple english too. And could u please tell us about this "many many" cars that went wrong? I'm yet to hear of "well looked after" new toyota engines going bust. I know quite a number of people using new toyotas in sri lanka but never heard any of them going bust.. Maybe its how these "many" cars are maintained. For your info, engine oil is not the only reason a new engine can go bust. There can be so many other factors. Running low octane petrol in an engine mapped for higher octane alone can damage an engine significantly. European vehicles are mapped to 95 octane or higher and japanese performance vehicles are mapped to 100 octane. Since u r aware of the conditon of petrol in sri lankan best is to get the ecu remap to somewherer around 90. Dust, high humidity can be a problem for engine electricals too. Give them some thought.

Machan what u said is correct. thats the reason u got piston rings. when u make the rings from a lower grade material than the liners u get the rings to wear out faster. thats the reason u have to put new piston rings every now and again. Pistons don't touch the liners but the rings do. oil rings actually scrape the oil from the liners thats y i said only oil left on the liner surface are the ones trapped in between hoaning lines. When i said negligible amounts i mean something like 1cc (cubic centimeter) of oil every hour or even less. And these oil will burn away rather than mixing with oil again.

Ok i will try to be considerate if u try not to be obnoxious. The reason I'm confident about synthetic oil is because I've learned enough about the molecular bonding of synthetic and ordinary mineral oil to know how they break. And for ur information most of the earlier synthetic oils were either semi-synthetic or a mixture of two different synthetic oils with different viscosities mixed to get the required viscosity. When these oils break, they break into two different viscosities. one thick layer of oil which is known as 'formation of sludging' and a very thin layer of oil. Both equally useless for the engine. This problem was found few years back by the oil manufacturers and they have brought solutions to it. (They actually did proper research ) Ur knowledge of piston engines is quite astonishing:D Makes me wonder who does these research for u For ur information each piston has 2 rings one is the piston ring and the other is the oil ring. Oil ring make sure that the chamber is free of oil at the time of ignition! Oil that is in the chamber are the ones that is trapped in between the hoaning marks of the cylinder liner. These are negligible amounts. Unless the rings are worn out there can't be any significant mixing of petrol and oil. Furthermore Low octane level won't affect the oil. And I would like to know what impurities are there in Sri Lankan petrol? I know the conditions in Sri Lanka is different. Thats y asked if anyone has a car with computer controlled service reminder built in, because it takes all that u mentioned into consideration.

what proof have u got to tell us that fully synthetic oil breaks after 8 months? our company cars (mostly VWs and Audis) do about 18,000 - 20,000miles before an oil change. that is not within an year. sometimes even 2 years!! VW told us that there is absolutely no need to change oil until the "Service" light comes on. some of these cars do about 200,000 with only 10 - 12 oil changes. so u telling us that u've done more research than the VW guys? There is no way in this world fully synthetic oil can break down in 8months if its NOT used!! The whole thing about synthetic oil is that it breaks down when it is used unlike mineral oil which tends to contaminate quite easily. The older your engine gets you can go onto semi syn and then mineral oils This is just ridiculus! I don't know who does these research! so u r telling me after 10 years time i should put mineral oil to my car because its old, even though the manufacturer recomends synthetic oil? Before u bring the whole "Sri Lankan conditions" thing here I would like to ask if anyone here from SL uses a car with computer controlled service reminder built in? Please let us know what intervals do u get and what kind of driving do u do?

The next Toyota Celica is to be built by Subaru, the Monday morning rumour mill has reported. It has been reported that the replacement for the Celica will arrive next year in Japan and is a joint effort between the two car makers. It is expected to come in two variants – a high-performance four-wheel drive GT-Four and a more sedate GT model. Toyota is hoping to put the GT on the market in the US for just over £10,000. It will feature a front- mounted, naturally aspirated 2.0 litre Subaru engine and rear-wheel drive. The pricier GT-Four is understood to be getting the same 300bhp turbo four seen in the Japanese-spec Impreza STI. Both cars could come in a coupe and three-dour hatch bodystyles. http://www.pistonheads.com/gassing/topic.a...23&t=493094 Toyota reliability with a subrau STI engine. Not a bad idea. Found this under comments.. Hillarious "Mmmmm pretty sure that they've discontinued "Celica" as a model (like mr2, corolla).. so that WOULD be interesting to see a subaru built toyota.. or is that a toyota built subaru.. or a tubaru.. or .. god, i'm confused."
